i need to use a for loop and continue indentifier to create a program that counts to 20 skipping the odd numbers. my approach is to use an if statement to decide if the current number is odd and continue back to the for loop (skip printing odd number).

however, i am struggling to figure out how to nest the if statement, and how to write the sytax for multiple conditions (if number is equal to 1 OR 3 OR 5 etc...)

here is my code:
CODE
#include <iostream>
using namespace std;

int main()
{
    //variables
    int icount;
    for (icount = 1; icount < 21; icount++)
    {
        {
        if (icount == 1,3,5,7,9,11,13,15,17,19)
            continue;
    }
        cout << icount << endl;
    }
}



and i get a blank output.

Better yet, check out the modulus operator (%) it will help you in this task tremendously!

even number % 2 = 0
odd number % 2 = 1

Test if it is 1 or 0 and then the magic world of modulus will open up to you. smile.gif

aha! modulus, finding the remainder after a division. i didn't think of that. thank you so much!

updated code:
CODE

#include <iostream>
using namespace std;

int main()
{
    //variables
    int icount;
    int check;
    for (icount = 1; icount < 21; icount++)
    {
        check = icount %2;
        if (check == 1)
            continue;
        cout << icount << endl;
    }
    system ("PAUSE");
    return 0;
}


and here is my output:
CODE

2
4
6
8
10
12
14
16
18
20
press any key to continue...
